CASING FOR CRUDE -OIL ENGINES-- To dll whom) it may concern:,

Be it known that I, DUDLEY R. MORRISON,

a citizen of the United States, residin at Hartford Cit in the county of Blac rd and State of lndiana, have invented certain new and useful Improvements in Casings for Crude-Oil Engines, of which the following is a specification.

his invention relates to improvements in j ournal-bearings for explosive-engines in which the inner end of the cylinder opens into a casin within which the pitman, crank, and cranks aft are located; and the object of the invention is to relieve the cap portion of the casing, which is removable topermit access from the full orce of the explosive impulses.

The object also is to provide means adjustable from the outside of the casing for taking ufp the wear at the main shaft-journals, t ereby saving the loss of time and the annoyance incident to the removal of the casing or other parts; and a further object of the in VGDtlOIl'lS to provide means for adjusting the j ournal-boxes without danger of leakage.

I accomplish the objects of the invention in the accompanying drawings, in whichj Figure 1 is a detail in side elevation of that part of an engine-casing which relates to my invention, showing my invention applied thereto. Fig. 2 is a vertical section on the dotted line 2 2 of Fig. 1. Fig. 3 is a detail, on a larger scale, showing the casing in side elevation with the cap partly removed and the associated parts entirely removed. Fig. 4 is a like view showing the ea in operative position on the casing, the sliiaft in place, and the adjustable follower and outside lower re movable plate assembled. Fig. 5 is a vertical section on the line 5 5 of Fig. 2, but on the same scale as Figs. 3 and 4; and Fig. 6 is a side view of the removable plate.

Like characters of reference indicate like .parts throughout the several views of the drawings.

7 indicates the main or body casing of the engine, which terminates on an oblique line through the axis of the main shaft, and 8 is the removable extension thereof which I designate as the ca 9 1s the main sha of the engine, and it is mounted on journals supported by the casing. A lower portion 10 of the journal-box is cast as an integral part of the casing 7.

In engines of this class the rapidly-recur- I Specification of Letters Patent.

ring explosions have'a powerful tendency-to open the joint between the body of the casing and th plosive force and tendency to open the oint of the casing, which produces leakage, I provide the integral extension 11, which fits within a housing 12, cast on the cap 8. The integral parts 10 and 11 together contain one half of the bearing for shaft 9. The opposite half is formed by a movable bearin -block or follower 13, which is located partly Within the housing 12 and the remainder able notch 14 in the casing 7. Spacingstri s 15 are placed between the follower 13 an the op osite half of the journal-bearing, and as the caring becomes worn by use one of the strips is removed, which allows the follower to be adjusted closer to the shaft. This adjustment is accomplished by means of the set-screw 16, which terminates outside of the casing, where it is accessible at all times for taking up any without removing the cap or opening up any of the parts. 'A j am-nut 17 prevents the working loose of the screw.

The housing 12 extends down on the side to the plane of separation between the body 7 and the cap 8, and therefore covers the ex tension 11 and the upper and major portion of the follower 13. A plate 19 is bolted to the outer face of the box 10 to fill out flush with the corresponding face of the housing 12. Leakage around the shaft 9 and at other joints is stopped by the packing 20, which is confined by the metal ring 21. The ring 21- is split at 22, the ends being feathered and lapped, as shown in Fig. 5. Surrounding the ring and coming in to the shaft 9 with an outer face is the cap 24, which is secured by bolts 25 to the housing 12 and through plate 19 to the box 10. Passing through the casing are the set-screws 27, here shown as four in number, spaced an equal distance apart and bearing at their inner ends against the ring 21. As the packing 20 becomes worn the ring 21 is reduced in diameter by screwing the set-screws 27 in against it, thereby compressing the packing into the leaking joints.

The construction above described is duplicated for the journals on each side of the housin Having thus fully described my invention, what I claim as new, and wish to secure by Letters Patent, is-

e cap, and in order to resist this ex in a suit-- looseness that may develop a separable cap united in a plane through the of which extend beyond said body into the cap, and an ad'ustable follower forming the opposite half 0 the journal-bearing.

2. In an explosive-engine, a body-easing and a cap joined on a plane through the axis of the crank-shaft, there being integral half journal-boxes extendin from the body-casmg into the cap, adjusta 1e followers forming op o site and remaining portions of the journa s, there being housings inte al with'the cap extending over the ourna -boxes down to the plane of the joint etween the body of the casing and the cap, removable plates to bring the lower parts of the boxes out flush with the housings.

Within which the adjustable half-boxes are located and set-screws passing through the walls of the housings into contact with the ad'ustable half-boxes.

n witness whereof I have hereunto set my hand and seal,.at Indianapolis, Indiana, this 30 6th day of October, A. D. 1905.
